How first-level divisions are governed in Russia

Federal subjects – regions, republics, krais, federal cities (89 claimed by Russia, including Crimea and four regions of Ukraine whose annexation the UN General Assembly does not recognise). Governor (head) directly elected in most regions; regional legislature directly elected. Regional laws, budgets, health, education, regional police co-ordination. Governors can now discipline and remove local administration heads in some cases.
